AI Technical Summary

Technical Problem

The connection between the liquid cooling plate and the module in the existing energy storage battery pack has problems such as complex assembly, high cost, poor sealing and low heat dissipation performance. In particular, the crossbeam structure occupies the effective heat dissipation area of ​​the cold plate, increasing weight and flow resistance.

Method used

The connection structure of aluminum extruded cold plate and diamond-shaped fastener is adopted. The threaded connection replaces the welding of multiple parts, which simplifies the process and improves the sealing performance. It is suitable for the highly integrated thermal management system of new energy vehicle battery modules.

Benefits of technology

It simplifies the assembly process, reduces costs, improves sealing and heat dissipation performance, adapts to lightweight requirements, and enhances the reliability and efficiency of connections.
